We have had our redfoot George Herman in a 36x18x12 enclosure since we brought him home last year. We have built him a new tortoise table so he will have lots of room for the long winter inside. It is 60x30x12. It is lined with corragated plastic and sealed with GE 1 clear silicone. Total build time for the table and enclosure was 6 hours. This is still a work in progress as we are going to add some plants and other things. He seems a bit confused at the moment but he will get used to it (I hope lol).
